MAX8865R

19-0485; Rev 0; 4/96 Dual, Low-Dropout, 100mA Linear Regulators MAX8865T/S/R, MAX8866T/S/R _______________General Description The MAX8865 and MAX8866 dual, low-dropout linear regulators operate from a +2.5V to +5.5V input range and deliver up to 100mA. At 200mA total load, the PMOS pass transistors keep the supply current at 145µA, making these devices ideal for battery-operated portable equipment such as cellular phones, cordless phones, and modems. The devices feature Dual Mode™ operation: their output voltages are preset (at 3.15V for the “T” versions, 2.84V for the “S” versions, or 2.80V for the “R” versions) or can be adjusted with external resistor dividers. Other features include independent low-power shutdown, short-circuit protection, thermal shutdown protection, and reverse battery protection. The MAX8866 also includes an auto-discharge function, which actively discharges the selected output voltage to ground when the device is placed in shutdown mode. Both d...
